T 0 all whom it may concern: I

Be it; known that we, FRANK PARDEE, Jr., and hliai'tTOPuE R. YANWV. LYON, citizens of the United States, and residents oi? Hazleton,

Pennsylvania, and Boston, Massachusetts,

respectively, have invented certain. new and useful Improvements in Spragsffor t -Sledding, of which the following isa specifics. tion.

This ii'ivention relates to a device used by those indulging in winter sports, such as sledding; and toboganning. Our sprag consists of a blade adapted to engage the slippery road sijlriace over which the wearer is traveling, and means for detachably fastening the blade to the foot of the wearer.

Our invention will be understood from the following specification when read in connection with the accompanying drawings in which similar reference characters denote similar parts in the several views.

Fig. .l. is a vertical longitudinal section through the sprag, parts being shown in elevation, and the foot of a wearer being shown in. broken lines;

Fig. 2 is a top plan of the sprag with the outline of a shoe shown in broken lines;

Fig. 3 is an end elevation of the sprag viewed. from the left of Fig. 1;

Fig. 4; is a view illnstratingthe use 01" the sprag.

i In the drawings 1 represents the blade of the spray; which is upturned at its forward end 2 and provided with serrations3 so as to enable the wearer to exert considerable friction on an icy road-bed to assist in steering the sled. The forward end of this blade is the widest part so thatit projects laterally beyond the toe 25 ot the shoe to which it is fitted, as shown clearly in Fig. 2. The blade is preferably of such length. that its forward end projects slightly beyond the toe of the shoe. The shank 4 of the blade is bent uwardlv to conform in contour sub stantially to the instep of a human foot,

and the extremity oi this shank isbent over this stirrup as formed of .a separate piece riveted .to the underside of the blade, it is to be understood that it iswithin our invention to form this stirrup integral with the blade by punching the entire article- :trom a flat sheetandforming it up in a suitable die. 7

To hold the sprag against endwise. displacement, we use a flexible member which is adapted to embrace. the ankle of the I wearer. As shown in the drawings, this flexible member comprises a rope 10 which is slipped under the hook 6 and held against movement in one direction by a knot 11 formed in the end thereof. At the opposite end this rope is provided with one or more knots, as shown alt-12 and 13, so that the.

tofore made to enable one to steer a sled or toboggan by means of a metallic member which was ixed to the shoe. This, of course, requires a special shoe for the purpose. Our improved sprag can be attached to any shoe and by means of the flexible member and the hook formed on the sprag it will be apparent that one size of device will fit feet of diflt'erent sizes.

Though we have described with great particularity of detail the specific embodiment of the invention shown, it is not to be infe fred that we are limited thereto as changes in form and modifications of arrangement may be made by those skilled in the art without departing from the invention as defined in the appended claims.

What we claim is:

1. A sprag for sledding having a surfaceengaging member comprising a substantially flat plate, having a surface engaging forward edge at least as wide as the toe portion of the wearers shoe, a stirrup secured below said member at a location to the rear of said forward edge arranged to support said surface engaging member in such position that the forward edge is located above and extends forward of the toe portion of the curing the spray to the shoe of the Wearers foot.

2. A sprag for sledding having asurface:

engaging member eomprisin g a substantially flat plate having an outer upturned edge; a stirrup securedto the underside of said plate and means for detachably securing the sprag to the foot of the wearer.

3. A sprag for sledding eomp'rising'a plate member having a surface-engaging portion with an "upturned serrated edge, means secured thereto for embracing the ball of the wearefs foot the plate member being secured to said last named means so that in use it is located above the toe portion of the wearei"s shoe and substantially parallel to I the sole of said shoe, and flexible means for detachably securing the sprag in place.

4;. A spra'g for sledding comprising a blade adapted to engage the road-bed over which the wearer is traveling, a stirrup secured to the undersideof said blade a shank secured to saidblade shaped to conform sub- .stantially t0 the contour or the instep of a foot and having a hook formed on the end thereof and a rope having knotted portions for engagement with said hook for detachshoe, and a member secured thereto having a forwardly extent-lin blade and a rearwardly and upward y extending shank shaped to conform substantially to the 0011- tour of a foot and having va hook portion for securing the article in place. a y

In witness whereof We have hereunto signed our names.
